Could not find local "typescript" package.The "@ngtools/webpack" package Angular 2

Question

I searched here, Angular 2, @ngtools/webpack, AOT, but does not worked for me. I ran the npm install command. What i'm doing is that i'm creating a new Angular 2 project. and while I run ng serve --open then I got the below error.

could not find local "typescript" package.The "@ngtools/webpack" package requires a local "typescript@^2.0.2" package to be installed.Error: Cannot find module 'typescript'

Any help will be highly appreciated.

Below is the stacktrace:

For the sake of not having answers in the comments section, here the error is self explanatory:

The "@ngtools/webpack" package requires a local "typescript@^2.0.2" package to be installed

So webpack needs typescript and you just have to install it.

npm install typescript@latest --save-dev
